as you can see, amanda is doing estimates, but then doesn't do dumps. what does this error message "(aborted:[request failed: timeout waiting for ACK])(too many dumper retry)" mean really ?

Are you really really sure the estimates were done on the client,and
not on the server?

The server side dumper sends a request to each client, and does not
receive an ACKnowkledge packet from that client within a reasonable
time.

I would take a look in the debug files on the client, usually in
the dir /tmp/amanda/.  There you can see files "amandad.datetime.debug"
which contain the packet received, and the replies.  If there
are no debug files, than amandad isn't even started.

Does amcheck pass all tests?
